Embodiment Construction

[0058] This invention relates to pressure tanks. The tank has a tubular portion and two bottoms positioned at each end of the tubular portion. The bottom allows the pressure tank to be hermetically closed and defines a fluid storage volume. The tubular portion comprises a cylindrical wall and at least a first layer of axial stiffening elements wound around the cylindrical wrap, which acts as a rigid base for the wrap. The modulus of elasticity of the material of the cylindrical wall is lower than the modulus of elasticity of the material of the first layer of circumferential reinforcing elements. Thus, the deformation of the cylindrical wall tends to bring the cylindrical wall into contact with the circumferential stiffening element, which thus helps to take up (withstand) the pressure. Thus, the thickness of the cylindrical wall can be reduced, since the circumferential stresses related to the internal pressure are taken up by both the cylindrical wall and the circumferenti...

Abstract

The present invention relates to a pressure vessel comprising a tubular portion and two bottoms (5), the bottoms (5) being arranged at the ends of the tubular portion. The tubular portion comprises a cylindrical wall (1) and a layer of circumferential reinforcing elements (2) wound around the cylindrical wall (1). In addition, the modulus of elasticity of the material of the cylindrical wall (1) is lower than the modulus of elasticity of the material of the first layer of circumferential reinforcing elements (2). The invention also relates to a system for storing and recovering energy comprising a compression means, an expansion means, a heat storage means and a compressed air vessel according to the features described above.

Description

technical field [0001] The invention relates primarily to the field of compressed air energy storage, but can also be applied to other pressure tank systems. [0002] For example, the generation of electricity from renewable sources with the help of solar panels or onshore or offshore wind turbines is booming. The main drawbacks of these means of power generation are intermittent production and possible mismatches between production cycles and consumption cycles. Therefore, means are needed to store energy during production to release energy during consumption periods. [0003] There are many techniques available to achieve this balance. [0004] The most well known of these is the Pumped Storage Plant (PSP, Pumped Storage Plant) using two storage tanks at different altitudes. During the flood phase, water is pumped from the lower tank to the upper tank. Subsequently, during discharge, the water is sent to the turbine in the direction of the lower basin. [0005] Differen...
